UNITED STATES PHILIP DI'EHII, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO THE SINGER MANUFACTURING COMPANY, OF NEW JERSEY.

FEEDING MECHANISM FOR SEWING=VIACHINES.

SPECIFICATION forming part of Letters Patent NO. 652,172, dated J une 19, 1900. Application iilecl October 24, 1899. Serial No. 734,678. (No model.)

To @ZZ whom fm/ay concern:

Be it known that I, PHILIP DIEHL, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Feeding Mechanisms for Sewing-IiIachines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to improve the construction of the feeding mechanism of a certain well-known class of sewing-ma chines to adapt the same to a higher speed than heretofore, as also to provide better facilities for lubricating some of the runningf parts.

In the accompanying drawings, Figure l is a bottom view of a machine embodying the invention. Fig. 2 is a sectional elevation taken through the vertical portion. of the arm of the machine. Fig. 3 is a detail view showing the feed-operating eccentric, its strap, and a portion of the feed connection or link; and Fig. 4 is a detail view of the feed connection or link.

Referring to the drawings, A denotes the bed-plate, and B the vertical portion of the arm of the machine. The driving-shaft C is journaled in the upper portion of the arm, as usual, and is provided with the shuttle-operating-crank c,.connected by a pitman c7 to a rocker e, which is in turn connected to the shuttle-operating rock-shaft G, located beneath the work-plate of the machine.

The driving-shaft C is provided with a feedoperating eccentric c', encircled by a strap 7b, having one or more sleeve-like ears 7i snrrounding an arm 712 at the upper end of the feed connection or link 71,3, which is joined by a link h4 with the feed-regulating lever 72,5, as is usual in the toggle feed mechanism which has long been in use in certain styles of Singer machines, the link or feed connection h3 being jointed at its lower end to an arm 7L6 at the rear end of the feed-operating rock-shaft hl, to an arm or arms at the forward end of which the feed-bar z' is jointed in the usual manner. The arm 7b2 of the feed connection or link and on which arm the ears of the ecchines to which this invention relates.

The feed-bar i' is raised and lowered in the usual manner by the rock-shaft 7c, having at its forward end an arm 7e', provided with a stud engaged by a fork on the feed-bar, said shaft having at its rear end an arm 7a2, to which is jointed the lower end of a connecting-rod 7c3, having at its upper end a strap encircling an eccentric c2 on the driving-shaft C.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination with the driving-shaft C having the eccentric c', the strap 72l provided with one or more ears 77,', the link or feed connection 7b3 having a portion encircled by said ear or ears, the feed-moving rock-shaft 7L7 with which said link or feed connection is joined, the feed-bar i, and means for raising and lowering said fecdbar.

2. The combination with the driving-shaft C having the eccentric c', the strap 7L provided with one or more ears 71,', the link or feed connection h3 having a hollow, lubricant-holding portion encircled by said ear or ears, and which hollow portion is provided with one or more oil-escape holes, as hs, the feed-1noving rock-shaft 717 with which said link or feed connection is joined, the feed-bar 1I, and means for raising and lowering said feed-bar.

In testimony whereof I affix my signature in the presence of two witnesses.

`PHILIP DIRIIL.
